If side x has a length of 15 cm and side y has a length of 4 cm, then which value below could be the length of side z?
A.
20 cm
B.
21 cm
C.
17 cm
D.
10 cm
Answer:
Step-by-step explanation:
You should start with 10. The problem with 10 is that if you add 4 to it, the sum is less than 15, so no triangle will form.
A and B won't work either 4 + 15 is 19. A and B are both longer than 19 so no triangle will form.
The answer has to be C. 4 and 15 make 19. That's more than 17 so a triangle will be formed.

The diagram below shows the contents of a jar from which you select marbles at random.
An illustration of a jar of marbles is shown. Four of the marbles are labeled with an upper R, seven of the marbles are labeled with an upper B, and five of the marbles are labeled with an upper G. The key identifies upper R to represent red marbles, upper B to represent blue marbles, and upper G to represent green marbles.
What is the probability of selecting a red marble, replacing it, and then selecting a blue marble? Show your work.
What is the probability of selecting a red marble, setting it aside, and then selecting a blue marble? Show your work.
Are the answers to parts (a) and (b) the same? Why or why not?
Answer:
A:
probability of red = 4/16 = 1/4
prob(blue) = 7/16
probability of red, then blue is (1/4)(7/16) = 7/64
B:
probability red = 1/4
probability blue = 7/15
probability of red, then blue = (1/4)(7/15) = 7/60
c) your decision
Step-by-step explanation:
i took the test
The solution is,
A. 7/64 is the probability of selecting a red marble, replacing it, and then selecting a blue marble.
B. 7/60 is the probability of selecting a red marble, setting it aside, and then selecting a blue marble.
C. the answer is no.
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
here, we have,
given,
There are 4 red marbles.
There are 7 blue marbles.
There are 5 green marbles.
There are 16 marbles in total.
A:
Answer = (probability of selecting a red marble)(probability of selecting a blue marble)
First, the probability of selecting a red marble.
probability of red = 4/16 = 1/4
probability(blue) = 7/16
probability of red, then blue is (1/4)(7/16) = 7/64
B:
Answer = (probability of selecting a red marble)(probability of selecting a blue marble)
First, the probability of selecting a red marble.
probability red = 1/4
probability blue = 7/15
probability of red, then blue = (1/4)(7/15) = 7/60
c) obviously,
7/64 ≠ 7/60
So the answer is no.

quadrilateral vwxy with vertices v(-2,-1) w(-5,-2) x(-8,-7) and y(1,-6): 18o from the origin
Given:
The vertices of a quadrilateral are v(-2,-1) w(-5,-2) x(-8,-7) and y(1,-6).
To find:
The vertices of the image of quadrilateral vwxy after 180° about the origin.
Solution:
If a figure rotated 180° about the origin, then the rule of rotation is
[tex](x,y)\to (-x,-y)[/tex]
Using this rule, we get
[tex]v(-2,-1)\to v'(2,1)[/tex]
[tex]w(-5,-2)\to w'(5,2)[/tex]
[tex]x(-8,-7)\to x'(8,7)[/tex]
[tex]y(1,-6)\to y'(-1,6)[/tex]
Therefore, the vertices of image of quadrilateral vwxy after 180° about the origin are v'(2,1), w'(5,2), x'(8,7), y'(-1,6).
which of the following equations is equivalent to log(y) = 4.876
Answer:
[tex]10^{4.876}=y[/tex]
Step-by-step explanation:
Logarithms are just another way of arranging an exponential equation! You know how you can rearrange the equation 2 + 3 = 5 as 5 - 3 = 2, or the equation 2 x 3 = 6 as 6 ÷ 3 = 2? With logarithms, you can do the same thing with an equation like 2³ = 8. As a logarithm, we would write this equation as log₂(8) = 3. Here, we call 2 the base, 8 the argument, and 3 the exponent.
Logarithms like the one in the problem with a base of 10 are just written as log, without the base written out. In the equation log(y) = 4.876, our base is 10, our argument is y, and our exponent is 4.876, so as an exponential equation, we would write it as
[tex]10^{4.876}=y[/tex]

An underwater robot takes pictures at an elevation of -8 5/12 m relative to sea level. What is the robot's elevation expressed as a decimal? Show your work.
PLZ HELP I WOULD REALLY APPRECIATE IT
Answer:
Step-by-step explanation:
i think it 8.45
Answer:
To solve this question, all we have to do is to convert - 8 5/12 to a decimal.
So we have: -8 5/12 = -8. (5/12)
This is equal to -8.41666... , where the 6 continues forever. You can express this by drawing a line above the 6, which indicates that it continues forever.

Step-by-step explanation:
From the simultaneous linear equation, we have the coefficient matrix as;
(3 4 5)
(2 -1 8)
(5 -2 7)
The x-matrix is Dx is given by;
(18 4 5)
(13 -1 8)
(20 -2 7)
Similarly, the y-matrix Dy is given by;
(3 18 5)
(2 13 8)
(5 -20 7)
Also,the z-matrix Dz is given by;
(3 4 18)
(2 -1 13)
(5 -2 -20)
Determinant of the coefficient matrix from online determinant calculator is;
D = 136
Determinant of the x-matrix from online determinant calculator is; Dx = 92
Determinant of the y-matrix from online determinant calculator is; Dy = 696
Determinant of the z-matrix from online determinant calculator is; Dz = 576
From crammers rule;
x = Dx/D = 92/136
y = Dy/D = 696/136
z = Dz/D = 576/136

During a sprint, a basketball player is traveling at +3 m/s. Four seconds later, the player is traveling at –5 m/s. The average acceleration of the basketball player over the last 4 seconds is:
Answer:
the average acceleration of the basketball player over the last 4 seconds is 0.5 m/sec^2
Step-by-step explanation:
The computation of the average acceleration is shown below:
= Change in velocity ÷ change in time
= 5 - 3 ÷ 4
= 2 ÷ 4
= 0.5 m/sec ^2
Hence, the average acceleration of the basketball player over the last 4 seconds is 0.5 m/sec^2
